I am not saying detaching a HEAD is a good solution, but I am saying it is a better solution than corrupting the submodule branch, such that commits are lost in the submodule, only to be recorvered via the reflog. > After all, there must have been a reason why the user had checked > out a branch and had pointed it at a specific commit (presumably, > so that further work would be done while on the branch, to make it > easier and safer to eventually push the result back to the upstream > of the submodule's project).

My long term plan is to introduce another type of symbolic ref, which references a gitlink in another repository, such that the submodule can have a clear distinction between "follows the superproject", "has its own authoritative branch" and "its detached HEAD can mean anything, e.g. historical submodule behavior" > Perhaps I misread the description; but that would mean the > description was prone to be misread and has room for improvement ;-) ok.
